Nonskidding insulated stool



Nov. 5, 1929. M. B. SALISBURY NONSKIDDING INSULATED STOOL Filed Jan. 9, 1928 Patented Nov. 5, 1929 PATENT OFFICE MOSES B. SALISBURY, OF CHICAGO, ILLINOIS NONSKIDDING INSULATED STOOL Application filed January 9, 1928. Serial No. 245,478.

My invention relates to insulating stools particularly for use by electricians or men working around high tension electrical equipment and has for its object the provision of a stool which shall be simple yet strong in construction, which will serve to insulate the person standing thereon from the ground even when it is raining and the top of the stool and the ground are wet.

It is also a purpose of this invention to provide a stool of this character which shall be entirely free of metallic parts to further aid in obtaining complete insulation between the top thereof and the ground.

More particularly it is a purpose of this invention to provide in connection with a stool having an insulating top such for instance as a rubber pad, a means for insulating the lugs supporting the stool so that even though water is dripping downwardly from the top over the legs, a dry insulating band is maintained about each of the legs.

Another purpose of the invention is to provide the insulating means for the legs with suction cup bottoms so as to prevent the stool from slipping when placed on a wet surface such for instance as a concrete floor or pavement.

It is also a purpose of this invention to so connect the legs of the stool to the top portion that weight of the person standing on the stool will not tip the same even though he is standing on one edge of the top.

Other objects and advantages of the invention will appear as the description proceeds in connection with the accompanying drawings. However, I wish it to be distinctly understood that I do not intend to limit myself to the exact details shown and described, but that I intend to avail myself of all such modifications as wbuld occur to one skilled in this art and as would fall within the scope of the claims.

In the drawings:

Fig. 1 is a top plan view of the device;

Fig. 2 is a side view; and

Fig. 3 is an enlarged sectlon taken along the line 33 of Fig. 1.

Referring now in detail to the drawings, the stoolis composed of the top portion 5 preferably made of well seasoned wood and having thereon a mat or cover 6 of rubber or other suitable insulating material which may be roughened on the surface to prevent slipping. The top portion 5 is supported on a pair of longitudinally extending wooden bars 7 and 8 and which are secured by gluing or other suitable means to the under face of the top 5. The bars 7 and 8 as shown clearly in Fig. 1 project beyond the edge of top 5 as at 9 and 10 at the sides and also at the ends as indicated at 10 and 11.

Directly beneath the corners of the top 5 the members 7 and 8 are provided with sockets as indicated at 14: to receive the reduced upper end portions 15 of the legs 16. These legs may be constructed of any suitable material but that preferably used is the standard five inch locust pin such as is used in mounting insulators upon the cross arms in electric transmission lines. The legs are held in position by means of a hard wood pin 17 extending through from the inner wall of the bars 7 and 8 across the socket 14 and into the bar 7 in the opposite wall of the socket as at 18. The legs 16 as shown clearly in Fig. 3 taper from the top down and the lower portion of the leg is screw threaded as indicated at 19 in order to receive the screw threads 20 on the flexible rubber insulating member 21. This member 21 is adapted to screw onto the legs and the socket therein is of sufficient depth to completely enclose the leg and bring the upper end 22 of the member 21 into engagement with the lower surface of the bar 7.

In order to prevent water passing downwardly from the top to the legs from completing a wet path over the surface of the member 21' to the ground and thus destroy its insulating effect, I provide the member 21 with downwardly and outwardly curved flanges or petticoats 23 and 24 which serve to direct the moisture outwardly away from the main body portion thereof. This construction maintains even in a driving rain a dry surface from the point indicated by the numeral 25 in Fig. 4 to the point indicated by the numeral 26 along the under surface of the petticoat 23 and downwardly along the body portion of the member 21 for a distance at least equal to the distance between the lower edge of the member 23 and its junction with the main body of the member 21. Similarly the flange 24: maintains a dry belt directly beneath it extending around the member 21.

The member 21 is also concave at the bottom as indicated at 27 to form a suction cup for the leg so that when the stool is placed on a slippery surface the legs will grip the surface to prevent slipping or sliding of the stool.

From the above description it is thought that the construction and advantages of this invention will be clear to those skilled in this art and having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. A protective device of the character described comprising a substantially flat top portion, a plurality of supporting legs therefor and flexible members of insulating material encasing said legs, said members having outwardly and downwardly projecting flanges thereon to maintain a dry section between the top and the bottom of said mem bers.

2. A protective device of the character described comprising a substantially flat top portion, a plurality of supporting legs therefor and flexible members of insulating material encasing said legs, said members having concave bottom ends and having outwardly and downwardly projecting flanges thereon to maintain a dry section between the top and the bottom of said members.

3. An insulating support and cover for the legs of a linemans stool comprising a flexible insulating member having a socket therein for receiving a stool leg, said member having a downwardly and outwardly extending annular flange intermediate its ends to direct moisture falling on the upper portion thereof outwardly away from the lower portion thereof and thereby maintain a dry section directly beneath said flange.

4. An insulating support and cover for the legs of a linemans stool comprising a flexible insulating member having a socket therein for receiving a stool leg, said member having a downwardly and outwardly curved annular flange intermediate its ends to direct moisture falling on the upper portion thereof outwardly away from the lower portion thereof and thereby maintain a dry section directly beneath said flange.

5. An insulating support and cover for the legs of a linemans stool comprising a flexible insulating member having a screw threaded socket therein for receiving a stool leg, said member having a downwardly and outwardly extending annular flange intermediate its ends to direct moisture falling on the upper portion thereof outwardly away from the lower portion thereof andthereby maintain a dry section directly beneath said flange.

6. An insulating support and cover for the legs of a linemans stool comprising a flexible insulating member having a socket therein for receiving a stool leg, said member having a downwardly and outwardly extending annular flange intermediate its ends to direct moisture falling on the upper portion thereof outwardly away from the lower portion thereof and thereby maintain a dry section directly beneath said flange, the lower end of said member being concaved to form a suction cup.

7. A linemans stool comprising a rectangular top portion, supporting legs for said top portion, means for securing said legs to the top portion with the centers of the legs aligning vertically with the corners of said top portion, and insulating elastic coverings for said legs having means to prevent water falling on said top or coverings from completing a wet path over the surface of said coverings to ground.

In witness whereof, I hereunto subscribe my name this 29th day of December, A. D.
